STAPLE-MACHINE.

- Specification of Letters Patent.

Application filed February 25, 1905- Serial No- 247.264.

Patented Dec. 11, 1906.

To all whom it may concern:

Be it known that I, ROBERT CoATEs, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, haveinvented certain new and useful Improvements in Staple-Machines, of which the following is a specification.

This invention is designed to provide an improved machine for forming and setting staples in the manufacture of paper boxes, leather goods, and the like. Its leading purpose is for cutting variously-shaped blanks from a metallic ribbon automatically fed thereto to form therefrom variously-proportioned .staples suitable to the use for which they are desired and to set the staples thus formed in a continuous operation. Plain metallic ribbons having the width required for the work in hand are used and staples are formed therefrom without waste of metal.

The nature and characteristic features of the improvements will appear from the following descri tion and the accompanying drawings in ilustration thereof, of which- Figure 1 represents a side elevation of a machine embodying the invention, parts being broken away to show the interior construction. Fig. 2 represents a side elevation of the same with the movable parts in a second position. Fig. 3 represents an end elevation thereof with parts shown in section to disclose the interior construction. Fig. 4 represents a sectional elevation of the feeding mechanism taken. in the plane of the feedrolls. Fig. 5 represents a bottom view of the die and ribbon guides. Fig. 6 represents a perspective view of a section of the die-guide and the knife. Fig. 7 represents a perspective view of mechanism for holding the female die and setting the staples. Fig. 8 represents a sectional elevation of the die mechanism and cooperating parts in position for forming the staple. Fig. 9 re resents a sectional elevation of the fema e die and cooperating parts in position for setting a staple. Figs. 10 and 11 represent sectional elevations at right angles to each other of mechanism for intermittently operating the feed-rolls, the knife, and male die. Fig. 12 represents a sectional view in the plane of the top of the die-guide. Fig. 13 represents a perspective view of the female die and the mechanism for reciprocating it, and Fig. 14

driven by the wheel represents a view of the several stages of the material operated upon in forming and setting a staple.

As shown in the drawings, the column 1 has the head 2 and supports the bearings 3 and 4, in which is journaled the shaft 5, 6. Fixed to the shaft 5 is a disk 7, and fixed to the disk is the cam 8, which is revolved with the shaft within the yoke 9, having the roller 10 riding upon the shaft and cam. The yoke has depending therefrom the rods 11 and 12, which carry the cross-head 13, having thereon the male die 14 and the knife-striking pin 15.

A cam 16 is fixed on the shaft 5 and engages a roller 17, carried by a rod 18, which is reciprocated longitudinally by the action of the cam upon the roller. A lever 19, fulcrumed by the bolt 20 on a stationary post 21, is connected by the pin 22 with the rod 18, by which it is oscillated. This lever is pivotally connected by a pin 23 with a slide or die carrier 24, having a T end 25, the slide reciprocating in ways 26 formed in the guide 27, which is fixed to the head 2. die 28 has the flange 29, which engages the ways 26, and the open socket 30, which is adapted to be'engaged by the T end of the slide, theslide reciprocating the die in the open throat 3 1 of the guide. A knife 32 is pivoted by the pin 33 on the guide and acts in shearing relation to the shearing-block 34 thereof, the knife being pressed down by the action of a spring 35, secured to the guide.

The knife is struck by the elevation of the pin 15 to cut a blank from a ribbon fed under the shearing-block 34, and the blank thus shorn is struck by the forming-pin or male die 14, which drives it u wardly into the female die 28, which is hefd in proper position therefor.

The disk 7 has the camroove 36 therein and a cam 37 thereon whic engage, respectively, the pin 38 and the roller 39 on the plunger 40, which reciprocates in the head 2, the plunger having therein a longitudinal way 41, engaged by a screw 42, set in the head for guiding it. The plunger has a reduced end 43, with a squared rib 44 and a pin 45 thereon. A compound socket or diecarrier 46, movable in the head 2, is fitted to the parts 43 and 44 and has a movement limited by the pin 47, fixed to the rib and work- A female ing in the recess 48 of the socket. In the socket are the ways 49 for engaging the flange 29 and the web 50 for engaging the top of the female die, which is engaged therewith by the slide 24 and carried downwardly therefrom b the socket to the anvil 50, supported by tie arm 51.

Fixed on the shaft 5 is a cam 52, which strikes and depresses a lug 53, attached. to a lever 54, having a fulcrum 55, the lever being elevated by a spring 56, connected thereto and anchored to the head. The lever has a piece 57 depending therefrom, to which is swiveled a link 58, having a pivotal connection with a bell-crank 59, rocking on the spindle 60, the spindle having fixed thereon a ratchet-wheel 61, advanced by a pawl 62, carried by the bell-crank. The spindle 60 has the roller 63 fixed thereto, which is journaled therewith in the feed-guide 64, in which is also journaled a feed-roll 65, the respective rolls having thereon the engaging gears 66 and 67 for operating them together. A bracket 68, fixed to the feed-guide, carries the spindle 69, by which the ribbon-reel 70 is journaled on the block and from which ribbon is drawn by the rolls to the knife 32. The feed-guide is pivoted upon the pin 14,

' which works therethrough and is supported by a bearing-lug 71, fixed to the die-guide. A slot 72 in the feed-guide, with the rod 12 passing therethrough, permits the feedguide to be oscillated about the pin 14 as a center and set, as by clamping the lug 71, so that the ribbon 73 may be fed at various angles to the knife 32.

It will now be understood that the several cams 8, 16, 36, 37, and 52 are so arranged on the shaft 5 that the several mechanisms operated thereby are timed in their action. The cam 52, acting through the intermediate mechanism, will cause the rolls 63 and to advance the tape 73. Upon the advance of the tape the cam 8, acting through the intermediate mechanism, elevates the pins 14 and 15. The pin 15 strikes the knife 32, which cuts a blank 74 from the tape, and in sequence therewith the pin or male die 14 strikes the blank, which is driven thereby into the female die 28 to form the staple 75. As the cam 8 descends the mechanism elevated thereby falls by gravity and through the action of the spring 13, and when the pin 14 has cleared the female die the latter is carried by the cam 16 and the intermediate mechanism into engagement with the socket 46, which is held in the elevated position. The female die being engaged in the socket, the cams 36 and 37 descend so that the plunger 40 and the socket 46 are carried downward until the latter rests upon the work held upon the anvil 50. When the socket and female die have reached the limit of their downward movement, the plunger continues to descend and the pin 45 passes through the female die, driving the staple and upsetting it to the form 76 in the work 77. he plunger now rises, lifting the socket and engaging the female die with the slide, which withdraws it to the initial position for a repetition of the operation.

Having described my invention, I claim- 1. In apparatus of the class described, a female die, mechanisms for reciprocating said die alternately in transverse directions, a male die, mechanism for inserting said male die in and withdrawing it from said female die when the latter is in one of the courses in which it reciprocates, and a pin that is entered and withdrawn from said female die when the latter is in the other of the courses in which it reciprocates, substantially as specified.
